Permittee Name: Permit No: Operation Name: Anniversary Date: Additional information Lakewood Brick and Tile Co. M- 1979 -045 Church Pit 02/28/2013 7. Total Disturbance 67.50 ac ± Clay Approximately 40.30 acres is disturbed by the clay operation in Stages 0, I and II. This included the old clay mined area south of the ditches shown as the Clay Processing Plant area (purple) and the active clay mining area north of the ditches (light blue). Gravel Approximately 27.20 acres is disturbed, 12.75 acres is being used as plant site area in Stage A (orange) and the remain- ing 15.00 acres is stockpile area. No gravel was mined this year. The material processed at the Plant Site came from gravel mined this year on the Rocky Flats Pit (M- 1987 -113). Some waste rock was removed for use by the mineral owners from the pre -law stockpile areas. 8. Clay No new area was disturbed this year as we continue to mine the area stripped in previous years. Mining will continue in Stage I or Stage II by mining deeper into the clay veins exposed in the past and advance the face to the north as needed. Stripping will continue over the clay deposit to expose additional clay in the area north of the ditches. The stockpiled clay on the east side of Stage II is being removed on a regular basis (tan). It is blended with the clay from this mine at our brick plant in Lakewood. Gravel Mining will continue to removed material between the Church Pit and the Rocky Flats Pit as approved in the permit. No sloping will be required along the permit boundaries on the east side of this mine. 9. No reclamation was required this year. The Pre -law stockpile areas that were disturbed have been graded so only resoiling and seeding will be needed when it is time for those areas to be seeded. Additional backfilling was done on the north side of Stage 0 (green) to facilitate relocation of the northern haul road. Stockpiles of growth medium are located along the west and south sides of the permit area (pink). 11. No reclamation is called for during the next year. However, backfilling may continue in the old clay pit area. The waste material from gravel processing will be used to construct the south mine slope from the original ground level to the pit floor. We will continue to fill the north slope of the old clay pit and begin to do sloping on the east side of Stage A if the gravel operator removes the overburden pile next to the face on that side. If the opportunities to sell rock from the pre -law overburden piles occur, that removal will continue as well. 12. Approximately 3.55 acres on the south section of the old clay mine has been backfilled over the life of the mine. The filled area is graded and used for working area in the Clay and Gravel Plant sites.
